While I’d like to think I’m a good storyteller and an artist, I’m pretty sure I’m not ‘awesome’ at either. That’s one more reason to pay attention to Augmented Reality (AR) these days.

As an engineer and a designer, I frequently find myself trying to explain a widget, a feature, or a design to someone. Often this takes lots of hand-waving, white-board markers, and innumerable sketches. This got better over time with improved drawing skills and communication techniques. It was even better still when I could put a physical model in someone’s hands by using a 3D printer for rapid prototyping. Well, things just got a lot more interesting when we started using AR through ThingWorx Studio to do virtual prototyping.

While I spend most of my time designing business strategies for the IoT and connecting products using ThingWorx as an IoT platform, the AR portion of ThingWorx is simply fun to use. One great way to employ the tool is to super-impose streaming data and information directly onto the product while looking through a mobile device. AR Prototyping, on the other hand, is the ability to superimpose alternate designs into the real world through a mobile device such that you can experience a design as it was intended. The kicker is that you can whip together a couple dozen designs, review them virtually — in person or remotely — and have a fabulous understanding of the design in less time than it takes to print even one prototype.

In the video below we’re playing with the app ThingWorx View by PTC. Watch this model of a motorcycle come to life with Augmented Reality (AR). We’ve used this technology for virtual prototyping. For some of our customers we are able to swap in and out CAD models to virtually prototype new designs and configurations.

So, if you’re like me and you want to convey a design idea in a hurry — even faster than a rapid prototype — you should really look into AR Prototyping. This has sliced-bread beat no problem.

If you want to start virtual prototyping, ask us how here! We’d love to help you transform the way you design and connect to your products.

The increased use of 3D printing, from hobbyists to professionals, has revolutionized the way ideas and products are brought to life. Multiple websites (GrabCAD, Thingiverse, etc.) provide over a million free downloadable files that can be printed on a variety of 3D printers. Everything from miniature drone blades to sci-fi figures to replacement parts for your vacuum cleaner are readily available. The possibilities for whatever application you have are almost unlimited. Almost. 

The key to giving your 3D designs unlimited potential for customization is CAD modeling software. While there are many accessible 3D printing files created by others, the most satisfying way to bring your ideas to reality are files created by you! Files for 3D printing can be created from scratch or existing files can by modified to suit your application. Without the ability to create unique parts, a 3D printer can quickly become a novelty. As soon as the excitement of first initial prints wear off, the use and return on investment reduces as well.

Engineering Services Customer Case Study

A company that customizes enclosure trailers recently proved to be an excellent example of this limitation and how to solve it. The company wanted to use an off-the-shelf LED lighting product to illuminate the interior of a racing trailer. They needed to mount the LED lights in a clean manner and in specific locations to satisfy the customer’s needs. The company also wanted to locate the lighting switches discreetly. Since these parts would not be mass-produced the cost of a plastic injection mold could not be justified. They decided a series of 3D printed components would be the best method to meet their needs within the given delivery timeline.

While the company had access to a 3D printer, they did not have access to CAD modeling software. Despite extensively searching online trying to fulfill the requirements for these lighting components, nothing could be found to suit their needs.

The company came across EAC and decided to utilize the Engineering Services Group to save the day. A member of the Engineering Services Team created several CAD models using PTC Creo to design the customized lighting components. Within two hours, the stylized CAD models were complete and ready for printing. Three days later the 3D prints were finished and installed in the trailer.

Figures 1 illustrates the CAD with 3D printing files and Figure 2 illustrates the finished parts installed in the trailer. The parts were 3D printed using the Form 2 by FormLabs. The Form 2 is a high-quality stereolithography (SLA) 3D printer. In this case, the parts were printed using a clear resin (GPCL02) and then painted black. The parts were quickly produced to provide the custom enclosed trailer with a lighting solution that exceeded the customers expectations.

This project demonstrates a practical application of 3D printing when paired with CAD modeling software. With PTC Creo and the Form 2, the Engineering Services team was able to quickly create finished and functional parts that can provide unique and differentiating products without the capital investment sometimes required by plastic injection molding and other manufacturing processes.

It’s important to remember that the quality of your print depends on the quality of your design. If the CAD model is poorly designed, your 3D printed product may have flaws. The cleaner your design, the cleaner your print. Luckily for you, we can help! Find out why you should design your products using PTC Creo here. If you think you already have a great CAD modeling software and want to explore the Form 2 instead, go here.

I applaud anyone currently considering how the Internet of Things (IoT) can transform their company and their approach to competition. This is what every industrial and consumer product company should be doing right now. While helping companies through the early stages of developing IoT strategies we’ve recognized a common challenge. Teams can get lost in the excitement of enabling their first “thing” and lose focus on their long-term vision and the value they can extract from streaming data. We get it! The IoT is exciting. That is why we always coach our clients to select an IoT platform (software) that allows them to quickly and easily develop applications that present valuable, digestible information to employees and customers – whether or not a role or data stream was part of the initial strategy.
This week provided me with a front row seat to unexpected value from streaming data. While working on an IoT proof of concept for a client, my team was able to refine a data stream and deliver a new application to an audience that was not part of the initial scope of the project. The only reason we were able to create this new application without charging an additional fee is because we selected ThingWorx, a solution by PTC as the application/mashup development tool. Thingworx helps teams create new applications in minutes.

I try to spend the majority of my time working on IoT strategies and how they can transform companies and competition. My background in engineering and software development provides me with a unique view into the time spent making things smart — providing sensor networks, communication layers, and ultimately enabling heretofore unseen analytics in real-time on remote products. The project the Connect Services team and I were working on this week involved developing mashups, which stemmed from earlier strategy work and team alignment. Mashups are the collection and presentation of data from smart things and systems enabling real-time business awareness and decision-making. For this project, we had already developed storyboards for the apps that would enable core product and service differentiation. Everyone was on board and excited.

Once the proof of concept device was wired and streaming data, we saw a whole new role that would benefit from the data that was streaming. Previously, the engineers would have been left hanging and the data would have been left alone and isolated. This is because developing an extra application for ancillary roles would have taken the project well off track. Leveraging ThingWorx as our application development environment, we were able to build a concept from scratch in literally seconds. What’s really cool is that it didn’t take any code at all either, just drag, drop, save, and we were in business. The concept made sense and in literally a couple of hours (not days or weeks) we had created an entirely new app and use case for the data. We were able to refine the data in real-time and create a whole new monitoring experience. Again, this was done without coding, just simply drag and drop.

So, here’s my recommendation — make sure your IoT platform supports your IoT strategy. And what’s more, be sure the platform you select is a tool that is flexible, fast, and fun — like ThingWorx. You will likely find more and more ways to consume, refine, and benefit from the data your connected products and enterprise produce just because it’s easy to do. And this, after all, is what your IoT platform should do — it should enable your existing business initiatives and accelerate your business initiatives.

EAC Connect Services is here to help you develop your IoT strategy, build and connect your proof of concept, and select the appropriate platform. Let us be your partner in the ever-changing world of the IoT. Please let us know if we can help you transform your business and help you beat your competition.

For some engineers, specifying a screw thread is no more than determining diameter and length and then searching through a parts catalog. For others, a custom thread is the difference between a successful surgical outcome with enhanced quality of life or a disappointing result that may require a revision surgery. A bone screw, whether used in a reconstructive, spinal, or other application, can be such an example.

A bone screw typically begins with a conical tip. The major diameter of the screw quickly increases to provide purchase in order to draw the screw into the bone. However, the minor diameter increases more gradually to reduce insertion force until the final portion is engaged into the bone. At this point the increasingly large tapered minor diameter provides a press fit into the outer (cortical) layer of the bone. This thread geometry is illustrated in Figure 1. The overall thread geometry is critical to providing stability to the affected area to allow bone growth and ultimately healing.

EAC’s Engineering and Design Services team recently worked on a project that clearly showed the advantage of using Creo versus SolidWorks to create this critical thread geometry. Several years ago the Engineering and Design Services team worked with an orthopedic company to create a series of bone screws varying in diameter and length for reconstructive surgeries. They used PTC Creo to create CAD models and drawings. The company was recently acquired by a global orthopedic corporation that used Solidworks 2016. The larger company insisted that the CAD models and drawings be recreated in SolidWorks 2016 for compatibility with internal corporate standards.

While working on the task, the Engineering and Design Services team found difficulty in reproducing the identical thread geometry using SolidWorks. Creo uses a single thread feature containing two individual sketches; one for thread profile and another for thread trajectory. This feature easily creates the varying thread tapers for the screw. Figure 2 shows the completed part and associated features in the model tree on the left hand side of the picture.

Recreating the same geometry in Solidworks requires 11 separate features and 8 sketches as shown in the model tree in Figure 3. Separate threaded features were required for the straight thread and the tapered thread at the tip of the screw. In addition, two helical curves were needed for each of the threaded features. One curve was required to provide the thread trajectory while the second helical curve was needed to fix the thread profile normal to the longitudinal axis of the screw.

The additional time to generate the needed features in Solidworks was significant for each part when compared to Creo and combined to substantial time savings for the entire project. This example illustrates why Creo is a superior application to SolidWorks.

The pressure to develop more and better products in less time is increasing. Your 3D CAD solution should enable you to provide your best work to produce your innovative ideas quickly and add advanced capabilities when you need them. The best tool for this is PTC Creo. PTC delivers the most scalable range or 3D CAD product development packages on the market today. Read more about why you should design using PTC Creo here.

Does the phrase “Formal Change Control” lead to scary thoughts like “We don’t have the time to set that up,” or “We don’t know how to do it or where to start?” If this sounds like you, likely your organization is spending more time dealing with the downstream and long term repeated issues than if they took the time to outline a change control process.

While every company will vary, there are three basic phases of creating a formal change control process. Find out how to implement a formal change control process in these three phases.

1. Issue or Problem Reporting
2. Change Request or Approval Process
3. Change Notice or Execution

Phase 1: Reporting & Logging Issues

• Provide an efficient way for anyone in the organization to report and log issues.
• Store issues in an Issue Queue that will resolved it in one of three ways:
  • Take no action
  • Put the issue on hold
  • Request a formal change

Phase 2: Formal Change Request

• The Formal Change Request is the second stage of review that can be handled in one of three ways:
  • Rejection
  • Request more information
  • Approved for further action, either fast track or Full Formal Change

• If the change is approved for further action, it typically is reviewed by a board that will do one of the following:
  • Reject the change request
  • Proceed to the change notice

Phase 3: The Change Notice

• At this point the change request can no longer be rejected, it must be addressed and acted upon.
• This phase can be defined as Static or Dynamic:
  • If it is a Static process, the same departments and teams will be notified and responsible for executing the change
  • If it is a Dynamic, a new process is developed specifically for each change

• When the plan is fully defined, typically a change implementation board review occurs.

Formal Change Control processes are simple, the added control of these processes alone could save your organization money in the long run. The possibility of increased productivity and reduced quality issues will far outweigh the initial time and resources required to get a change control process implemented.

We like to keep it simple, not scary here at EAC. For a full overview of how to design an effective change control process, download our eBook, Designing an Effective Change Control Process.
